Description
TER Limitex AG series is an explosion proof rotary limit switch. It is rugged and reliable and used to control the movement of industrial machinery in potentially explosive environments. ATEX rated.
Limitex AG Rotary Limit Switch Features:
- It consists of a gear moto that transfers movement through a primary input reduction stage (worm gear and helical toothed gear) and one or more secondary output stages (pairs of straight toothed gears).
- Accurate adjustment of cams by use of screws.
- Positive opening NC contacts for safety functions.
- Mechanical life of switches: 1 million operations.
- IP protection degree: IP66.
- Extreme temperature resistance: -50°C to +60°C.
- It features rugged external enclosure made of G20 cast iron, stainless steel transmission and gear driving shafts, self-lubricating technopolymer gears and driving bushes.
- All materials and components used are wear resistant and guarantee protection of the unit against water and dust.
Options
- Revolution ratios from 1:15 to 1:499, achieved by combining different secondary output stages.
- Snap action switches with 1NO+1NC change-over contacts.
- It can be equipped with a cam set with 2-3-4 switches.
- Available with flange for direct coupling to the motor.
- Available with direct control switches to enable direct action on the motor.
Certification
- CE marking and EAC* certification.
- ATEX certification EN 60079-0:2009, EN 60079-1:2007, EN 60079-31:2009.
- Conformity to Standards IECEx IEC 60079-0:2011, IEC 60079-1:2007-04 and IEC 60079-31:2008.
Products belonging to TER ATEX series are suitable for hazardous, potentially explosive areas. Hazardous areas are places where, under certain conditions, explosive atmosphere may form. An explosive atmosphere is a mixture of air and gases, vapours, fumes or combustible dust, whose combustion spreads rapidly (explosion) after ignition at atmospheric pressure. Users are responsible for carrying out a classification of hazardous areas, as set out in European Directive 1999/92/EC. International standards IEC 61241-10 provide criteria for classification of hazardous areas depending on their chemical nature, physical characteristics and quantity of substances used, as well as on the frequency and length of time when an explosive mixture may occur.
TER’s aim is to simplify the control of the machines equipped with its devices, designing reliable, ergonomic and intuitive safety products, capable of predicting the demands of the market and becoming the industry benchmark.
At the basis of this company mission is the will to establish a connection between market and company, by giving an increasingly central role to the sales department, seen as a continuous relationship between TER and its customers.
